Perazim
Fausset's Bible Dictionary [1]
Isaiah 28:21, "Jehovah shall rise up as in Mount Perazim," namely, as He broke forth as waters do, and made a "breach" (Ρerazim ) on David's foes at Baal Perazim by the valley of' Rephaim ( 2 Samuel 5:20). (See Baal PERAZIM.) So utter and sudden was the rout that the Philistines left their idols behind, and David burned them ( 1 Chronicles 14:11). "Mount" thus connected with "Baal" implies it was an idolatrous high place. Isaiah's reference to it as type of Jehovah's most sudden and overwhelming judgments shows how much heavier a blow it was than would appear from the incidental notice of it in 1 Samuel and 1 Chronicles. Josephus (Ant. 7:4, section 1) says not only the Philistines but "all Syria and Phoenicia, and many other warlike nations beside," made the attack on David.
